The Sony Xperia U was launched in May this year and has a dual core processor at 1GHz and this is a good start. The Xperia U stands out with its 3.5 inches screen in 16:9 format, and its desgin with rectangular shape and sharp edges. It’s a mid-range phone with high-end claims. A good thing at Sony is that they are making different phones besides the other smartphone on the market. The Sony phones are unmistakeable.
On the upper front side of the phone we find the proximity and light sensors, the main speaker and a VGA camera. At bottom we can see three touch sensitive buttons(back, home, menu) ; this buttons are indicated by 3 dots because they are embedded in the casing. The rear side of the phone has a secondary speaker, the 5MP camera, a LED flash and back panel is slightly curved.
The left side of the Xperia U features an microUSB slot while the right side has the power button, volume keys and a dedicated camera button. The phone doesn’t have a slot card and the SIM can be introduced without taking out the battery.
The Xperia U has a 3.5 inches display with a very good resolution at its dimensions; 480×854 pixels and 280ppi pixel density( a density which many smartphones in this class doesn’t have it). The display is LED-backlit LCD with multitouch up to 4 fingers Sony Mobile BRAVIA Engine and a scratch resistant screen(not Gorilla Glass). The resolution, high pixel density, good viewing angles and color reproduction tells us that the Xperia’s strong point is the screen.
Sony is making good camera phones and this can be seen at the Xperia U too. The 5MP camera with LED flash and with the experience that Sony has we don’t need to be afraid about making photos. the Xperia U can make good photos even in hard conditions. It has features like geo-tagging , autofocus, touch focus, face and smile detection, 3D sweep panorama, image stabilization and many other options in settings. Video recoding is made at 720p resolution and LED light can be used.
Xperia U comes with Android 2.3.7 Gingerbread and Sony panned an update to Ice Cream Sandwich. Sony has customized the interface and no traces of Gingerbread can be found. You can make a screenshot without using a dedicated application simply by keeping pressed the power button until a pop-up menu appears and there you can select screenshot option. In conclusion you can say that Sony’s user interface is like a custom rom.
The Cortex-A9 dual core processor is clocked at 1GHz and is based on a STE U8500 chipset. GPU is Mali-400MP with a 512 RAM support. Internal storage has 8GB and only 4GB are available to the user, a big minus considering that a slot card is not available.
Mobile data connection can be made in 2G EDGE speed up to 296 Kbps and in 3G with HSDPA speed of 14.4 Mbps. Wi-Fi supports b/g/n protocols, Hotspot and DLNA. Bluetooth is v2.1 with A2DP + EDR and usb connection is made by a microUSB slot with USB on-the-go support.
Making phone calls, listening to music, watching videos on Youtube, playing games, browsing on internet, using social media apps and using the camera can make the Xperia U to stay awake about 30 hours. It has a 1320 mAh battery but it has good autonomy for such a low voltage.
Overall the Sony Xperia U is a good smartphone with a good photo camera, an excellent display and good hardware configuration.
